CHAIN-PUMP.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed June 19. 1906. Serial No. 322.490.

To all whom it may concern:

Be it known that 1, CHARLES J. WILLIAMS, of Prosser, Benton county, andState of Washington, have invented certain new and useful improvementsin a chain-pump for the elevation of water for irrigation and to liftwater to relieve and clear mines, the pum being for mining irrigating puoses; and do declare the following to be a fu l and clear description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to the means and devices for pumping water;specially in connection with irrigation and mming, where water underpressure is not required.

The object of my improvements is to provide simple, inexpensive andeflicient means for the purposes herein mentioned.

In the accompanying drawing, Figure 1 is a side elevation of my improvedpump Fig. 2 p is a top plan view thereof; Fig. 3 a cross section takenon line 3 of Fig. 2 and viewed in the direction of the arrow Fig. 4 ahorizontal section on line 4 of Fig. 1 and viewed in the direction ofthe arrow; Fig. 5 a side elevation, artly in section, of the chaincarrying wheel Fig.' 6 is a longitudinal section on lines 6 of Fig. 1and viewed in the direction of the arrow.

Like letters of reference denote similar parts in the several figures.

P is a pump stock providedat its lower end with a cut-away portion P andat its lower end with a spout H. The stock P is closed at its upper endby a flanged cap G bolted to the su porting frame work M and serving tohold the stock in true vertical line. At the bottom of the stock P Iprovide a circular flange P encircling the stock and the flange has apair of upwardly extending angular brackets J provided at their endswith j ournal bearings J in which are journaled the shaft S of the lowerpair of chain carrying Wheels F.

Q, are metallic bands which are formed into two hoops with a centralconnecting web as best shown in Fi 4, one of the hoops of these bandsencirc e the stock P intermediate its ends and in the other hoops ofthese bands are mounted the stri s I whlch form a guide for the bucketsas wi hereinafter appear.

M designates a rectangular frame to the under side of which the flange Gis attached by means of the bolts G. L is a second frame similar to theframe M and adapted to rest upon the same. KK are a series of boltspassing through the frameL and hav ing their lower ends resting aboveplates 0 mortised into the upper surface of the frame M. N are tappednuts mortised into the under side ofthe frame L through which the boltsass. By this construction it will be seen t at the frame L can beadjusted toward and away from the frame M for the purpose of tighteningthe tension on the bucket carrying chains in a manner to be hereinafterdescribed.

R designate a pair of bearings mounted on the upper side of the frame Lin which is mounted the shaft R having at one end the gear A with whichmeshes the gear B on the shaft T mounted in bearings T which are alsosupported on top of the frame L. I C is a driving pulley also carried bythe shaft T. From this it will be seen that when power is applied to theulley C in any suitable way the shaft R will e driven through the gearsA and B.

F are a pair of chain carrying wheels mounted on the shaft R in linewith the pair of chain carrying wheels F mounted upon the shaft S.Running over these wheels are the pair of chains E upon which aremounted the buckets D which preferably are of the construction shown inFigs. 1 and 5. Preferably and as shown, the chains E are in sections andare connected to the buckets by means of the U -shaped bolt V passingthrough the bottom of the bucket and having a plate U passing over thefree ends of the bolt V and secured in place by means of suitable nutson the ends of the bolt. One section of the chain bein attached to theloop of the bolt V and t e section of the chain on the other side of thebucket being attached to the plate U at the ends of the bolt. Preferablyand as shown, the wheels F and F are provided with a peripheral groove Fin which the chains run and are also provided with one or more sectorshaped o emngs F in their periphery into which t e buckets extend, asclearly shown in Figs. 1 and 5. the buckets are so placed a art upon thechain and the wheels F and E are of such a size that but one slot isneeded on the periphery of each wheel. If the buckets were set closertogether it would, however,

as will be readily understood, be necessary to provide more slots in thewheels.

From the above description of the constructlon of my invention it willbe apparent In the form of construction shown that when power issupplied to the pulley l a stock, of a guide formed of a plurality ofthe wheels F will be driven and will carry the pump carrying chain downthe guide-way formed by the strip 1 in to the cut-away portion of thestock I and thence up the stock.

By providing the two frames L and M with their adjusting means it ispossible to take up any slack in the chains by merely setting up thescrews K. This adjustment being located at the top of the pump rendersthe same readily accessible irrespective of the location of the loa erend of the pump.

As will be noted by my construction of pump, the structure is entirelysuspended and supported from its upper end and no side bracing of thepump stock is required, and the connections between such pump stock andthe chain guides are such that each serves to preserve the true verticalalinement of the other, and the bucket carrying chain is caused totravel in a true line throughout its entire path.

While I have described what I believe to be the preferred form of myinvention, I desire to have it understood that many changes may be madein the form, construction and arrangements of parts without departingfrom the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is 1. In achain pump, the combination with l l l separated strips, hoopssurrounding the strips to support the strips in position, and meansextending from the hoops and engaging the stock to hold the guideparallel to the stock.

2. In a chain pump, the combination with a frame, a stock supported fromthe frame, a second frame mounted over the first frame, means foradjusting said second frame toward and away from the first frame, chainoperating mechanism including a chain pulley upon the upper frame, asecond chain pulley secured to the lower end of the stock and a pumpchain extending over said pair of pulleys.
